What program is it your trying to get rid of ?
You can also try downloading the Windows Installer Cleanup Utility at
How do I uninstall Office 2003, Office 2007 or Office 2010 suites if I cannot uninstall it from Control Panel? It will show you all the programs on
your computer and may give you a better chance of uninstalling it...
If not, let me know, we'll try another angle of attack
